R中的日期时间格式转换

Question

I read couple questions/answers here, but I can't seem to fix a date time problem.

How do I convert the dates 6/18/14 10:55 AM to 2014-06-18 (yyyy-mm-dd)? So, I just have dates at the end not time.

Below is what I have done:

data <- data.frame(date = c( "6/18/14 10:55 AM", "10/8/14 3:10 PM",  "10/31/14     12:24 PM","6/18/14 10:55 AM", "12/2/14 12:52 PM", "11/24/14 12:31 PM"))
str(data) #variable is factor 

data$date <- as.POSIXct(data$date)

data #Preview 

(Also I am not able to add the above code in code format for stackoverflow. Sorry for inconvenience).

Answer 1

With the help from above users, figured the problem. as.Date(data$date, "%m/%d/%Y") works. %Y should be capital.
